If you have lots of projection (eg if you have a very pendulous shape), you may also find that the calculator overestimates cup size - this is because, when leaning forwards, your breasts may project much further out from your chest than they would in a bra, with your bust circumference measuring larger than the volume you really need. See Bratabase to check the measurements of your bra against other bras before buying! Breast Shape Characteristics Shapes that can Contribute to Overestimation in Cup SizeĬonical breast shapes or shapes without a lot of upper or lower fullness can cause the calculator to overestimate as you are measuring around the fullest part of your breasts, but you don't have as much fullness as the average breast shape - the calculator is expecting more breast tissue than you have around the nipples, so you may need a smaller cup volume than the calculator predicts. Most people will have at least some of these characteristics, the more you have increases your chances of having the calculator over or underestimate cup size for you.Īlso note that while bras tend to be consistent in size, there is some variance between models.
